Abstract

The aim of this study was determine the selectivity properties of trammel net which have 100, 110, 120, 130 and 140 mm mesh size for Cyprinus carpio in Manyas Lake. Fieldwork was carried out in two different stations of Manyas Lake, in a monthly period from April 2007 to March 2008 and with a total of 24 catching trials. The SELECT method was used to determine the selectivity parameters. In the experiments, 208 C. carpio with length ranges between 28.4-65.4 cm were caught. According to the Lognormal model, the optimum total lengths were determined as 39.05, 42.95, 46.85 and 50.76 cm for 100, 110, 120, 130 and 140 mm mesh sizes respectively. As a result, in terms of the length at first maturity and legal status, the mesh size of nets used for C. carpio catching in Manyas Lake should not less than 120 mm

Özet

Bu çalışmanın amacı 100, 110, 120, 130 ve 140 mm göz açıklığındaki fanyalı uzatma ağlarının Manyas Gölü'nde sazan balığı avcılığındaki seçicilik özelliklerini belirlemektir. Saha çalışması Nisan 2007 ile Mart 2008 arasında aylık olarak toplam 24 avcılık operasyonu ile yürütülmüştür. Seçicilik parametrelerinin belirlenmesinde SELECT metot kullanılmıştır. Deneme süresince 28.4-65.4 cm boy aralığında 208 adet C. carpio yakalanmıştır. Lognormal modele göre yapılan hesaplamalarda 100, 110, 120, 130 ve 140 mm göz açıklığındaki ağlar için optimum yakalama boyu aynı sırayla 39.05, 42.95, 46.85 ve 50.76 cm olarak belirlenmiştir. Sonuç olarak ilk üreme boyu ve yasal statüye göre Manyas Gölü'nde C. carpio avcılığında 120 mm göz açıklığının altındaki ağlar kullanılmamalıdır
